Patent GB-909379-A (GB)
Title: Polymer coated fabric
IPC: D06M15/256
Filed: 1961-05-16
Abstract: A graphite fabric, comprising fibres consisting essentially of carbon atoms arranged in the crystal form characteristic of graphite, may be made by the carefully controlled pyrolysis of a woven or nonwoven fabric of organic fibres, preferably cellulosic fibres, e.g. rayon fibres.  The fabric may be a knitted fabric, a water-leaf fabric, or a web of cross-laid carded fibres or continuous filaments, which web may or may not have been passed through a needle-loom.  The graphite fabric may be produced by gradually and uniformly heating a rayon fabric, preferably in an inert gas, to a temperature sufficient to remove substantially all of the non-carbon components of the rayon and to cause pyrolytic conversion of the rayon to carbon.  The graphite fabric may be impregnated and/or coated with solid fluoroethylene polymer and may be used in a self-lubricating bearing.

Patent GB-183425-A (GB)
Abstract: 183,425. Eberts, E. C. July 19, 1921, [Convention date]. Feeding-devices for granular and like materials. -Relates to stock-dividers of the type in which a supply of pulverous or granular material is divided into proportionate parts, the material being fed continuously into an intermediate feedopening in a cylindrical casing and discharged on opposite sides. The division of the material is effected bv a rotatable divider-wheel 3 in the casing 2 below the feed-opening 1<a> and having segmental receiving-chambers disposed on opposite sides of the axis of the opening 1<a> and designed to communicate alternately with the opening 1<a> and to discharge the material into the discharge passages. The wheel 3 consists of two sheet-metal segments 3<a>, 3<b> placed reversely to each other and having a central disc portion 3<c> joined to the truncated edges for connection to the hub 4a. Transverse walls 3<d> connect the adjacent edges of the segmental portions. In the wheel shown in Figs. 1 and 3, the portions 3<a>, 3b are of equal area to divide the material into equal parts. The wheel may be fitted with deflector wings 3<h>. Fig. 4 shows a wheel to divide the stock in the proportion of 2 to 1, the segment 3<e> being twice the size of the segment 3<f>. To divide the material into four equal parts, it is first divided into two equal parts by the divider shown in Figs. 1 and 3, and then each stream is again divided by a similar divider. For dividing stock into three equal parts, the divider shown in Fig. 4 is used and the larger stream sub-divided by the divider shown in Figs. 1 and 3. Fig. 5 shows a wheel with four pockets and formed from a single blade of sheet metal, the edges of the segmental portions being turned towards each other and overlapped and secured together to form the division walls as at 3i. Deflector-wings 3<k> extend diagonally across the outer portions of the pockets. The apparatus is specially applicable for use in connection with the feed of grain &c. to grinding-mills, and for feeding material to sifters, reels, purifiers, or other machines or apparatus where division is desired.

A gear ring 122 on ring 116 is engaged by a gear wheel 124 driven through universal joints 174, 172 and an intermediate telescopic flexible coupling 94 by a servomotor (152 Figures 3 and 7, not shown). Rotation of the motor turns ring 116 to turn the work about the needle 44, the motor being operative only when the needle is in the work and the feed dog therefore disengaged from the work.

Title: Improvements in or relating to the preparation of allyl phosphites
Inventor: KENNEDY JOHN
IPC: C07F9/143
Filed: 1954-06-23
Abstract: A method for the production of diallyl or triallyl phosphite includes the steps of slowly mixing a mixture of substantially equimolecular proportions of allyl alcohol and a tertiary amine base with a reacting proportion of phosphorus trichloride at a temperature of about 0 DEG  C. or lower, the mixing being accompanied by stirring and the reaction mixture being then caused or allowed to attain ordinary temperature.  When triallyl phosphite is the desired end product a mixture of three molecular proportions of allyl alcohol and of a tertiary amine base are used with one molecular proportion of phosphorus trichloride whilst if diallyl phosphite is to be prepared a mixture of two molecular proportions of allyl alcohol and of a tertiary amine base are used with one molecular proportion of phosphorus trichloride and when the reaction mixture has attained room temperature a further molecular proportion of allyl alcohol is added and the mixture allowed to stand.  In each case the final mixture is separated from the deposited tertiary amine hydrochloride and the triallyl phosphite or diallyl phosphite distilled off under reduced pressure.  The reaction may be carried out in an inert diluent, e.g. benzene.  In examples: (1) a mixture of 3 mols. of allyl alcohol and 3 mols. of triethylamine is added to a solution of 1.5 mols. of phosphorus trichloride in benzene at 0 DEG  C. with vigorous stirring and after allowing the temperature of the mixture to rise to room temperature a further 1.56 mol. of allyl alcohol is added.  After allowing the mixture to stand overnight the deposited triethylamine hydrochloride is filtered off and diallyl phosphite recovered from the liquid reaction product by first washing the latter with water, drying over anhydrous sodium sulphate and then distilling under reduced pressure in the presence of hydroquinone; (2) a mixture of phosphorus trichloride (1 mol.) and benzene (2 mols.) is added slowly to a mixture, cooled to -20 DEG  C., of 3 mols. allyl alcohol, 3 mols. of triethylamine and about 11 mols. benzene.  The resulting mixture is allowed to stand until it is at room temperature and the triethylamine hydrochloride filtered off. The filtrate is then washed with water and sodium carbonate solution and finally distilled at reduced pressure in the presence of hydroquinone to recover triallyl phosphite.
